Embodiment 1

[0029] figure 1 It is a schematic flow chart of a method for waking up a vehicle audio system provided by Embodiment 1 of the present invention. This embodiment is applicable to the scene where the user wakes up the vehicle voice system, and the method can be executed by a wake-up device of the vehicle voice system, which can be composed of hardware and / or software, and can be integrated in the vehicle. Such as figure 1 As shown, the method specifically includes the following:

[0030] S101. When the user's audio data is collected, determine whether there is a wake-up word audio segment in the audio data. If yes, execute S102; otherwise, execute S105.

[0031] Wherein, the user may refer to the driver in the car or other users other than the driver, etc., which is not specifically limited here.

[0032] In the embodiment of the present invention, the wake-up word is used to wake up the vehicle voice system from a dormant state to a working state. For example, "Hey, Hongqi"...

Embodiment 2

[0049] figure 2 It is a schematic flowchart of a method for waking up a vehicle voice system provided by Embodiment 2 of the present invention. Optimizing on the basis of the above embodiments, specifically, determining whether there is a wake-up word audio segment in the audio data includes: determining the similarity between the audio waveform diagram of the audio data and the wake-up word audio segment waveform diagram; according to the similarity and the similarity threshold, determine whether there is a wake-up word audio segment in the audio data. .

[0050] Such as figure 2 As shown, the method is as follows:

[0051] S201. When the user's audio data is collected, determine the similarity between the audio waveform diagram of the audio data and the audio waveform diagram of the wake-up word.

[0052] Wherein, the wake-up word audio waveform diagram is pre-generated according to the voice wake-up word.

[0053] Optionally, after the user's audio data is collected,...

Embodiment 3

[0063] image 3 It is a schematic flowchart of a method for waking up an on-vehicle voice system provided by Embodiment 3 of the present invention. On the basis of the foregoing embodiments, this embodiment is further optimized. Specifically, after waking up the vehicle-mounted voice system according to the audio segment of the wake-up word in the audio data, it also includes: receiving a voice control instruction sent by the user to identify the voice control command, and controlling the vehicle-mounted voice system to execute Operate accordingly. Such as image 3 As shown, the method is as follows:

[0064] S301. If the voice control instruction sent by the user is acquired, recognize the voice control instruction to obtain a recognition result.

[0065] Optionally, after the vehicle-mounted voice system wakes up, the voice control command sent by the user can be collected in real time through the microphone, and then the acquired voice control command can be voice-recog...

Abstract

The embodiment of the invention discloses an awakening method and device of a vehicle-mounted voice system, a vehicle and a medium. The method comprises the steps that when audio data of a user are collected, whether an awakening word audio segment exists in the audio data or not is determined; if so, determining whether an adjacent audio segment exists in the wake-up word audio segment or not; and if not, awakening the vehicle-mounted voice system according to the awakening word audio segment. According to the embodiment of the invention, the false awakening rate of the vehicle-mounted voicesystem is reduced, and the awakening accuracy of the vehicle-mounted voice system is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of vehicles, and in particular, to a wake-up method, device, vehicle and medium of a vehicle voice system. Background technique [0002] With the development of intelligent technology, intelligent voice interaction technology has been widely used in various fields, especially in the automotive field. When the user uses the vehicle voice system, it is necessary to wake up the vehicle voice system first. In related technologies, the user wakes up the vehicle voice system by inputting a voice wake-up word, and controls the vehicle voice system to perform corresponding operations through voice control commands. [0003] The above method of waking up the vehicle-mounted voice system is to recognize the voice wake-up word input by the user, then when the user talks about the wake-up word while talking with other users, the vehicle-mounted voice system will wake up based on the wake-up wo...
